Triac, SCR Output Optoisolators Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Availability is restricted to existing stock or third-party distributors. Verify the authenticity of sources carefully, as counterfeit parts may circulate in the market for discontinued items. Ensure that any substitute components meet the original electrical specifications and pinout requirements before integration into production lines.

Triac, SCR Output Optoisolators Selection Notes

Engineers should evaluate alternative devices from the same manufacturer family due to the discontinuation status. Consider parameters such as holding current, trigger current, and isolation voltage when selecting replacements. Verify that potential substitutes support the required operating temperature range and package dimensions to maintain compatibility with existing PCB layouts and thermal management strategies.

Triac, SCR Output Optoisolators Part Context

The FODM3010R3 belongs to the FODM30 series of Triac output optocouplers. This series is designed for general-purpose AC switching applications where galvanic isolation is required. The specific R3 suffix indicates a reel packaging format. The device integrates an infrared emitting diode coupled with a photosensitive triac structure to facilitate signal transmission across the isolation barrier.
